Vision: I love this picture c: The setting makes me thing of Shining coming to their bed chamber to find his lovely wife. Not much more to say here, 5 stars.
Originality: 4 stars, because you HAVE done socks for ponies before.
Technique: The only flaw I see here is her shortness. She is normally very tall, so she looks a bit like a filly here. 4.5 stars.
Impact: As said before, she looks like a filly. This MAY cause some anger in your fans and such, so 4.5 stars.
Sorry if this isn't too helpful or detailed. I've not done many before but I've tried!
